Alternate cultivation technique of konjac and corn

Abstract

The invention provides an alternate cultivation technique of konjac and corn, which is realized by planting the konjacs on one surface of a furrow and planting the corns on the other surface of the furrow in the first year, namely, the konjacs and the corns are planted alternately; and in the second year, planting the konjacs on the surface which is used for planting the corns last year and planting the corns on the surface which is used for planting the konjacs last year; the planting density of the konjac is six rows per furrow, the row width is 0.3 meter, and the planting distance is 0.25 meter, the konjacs are sowed when the spring temperature rises to over 10 DEG C or in the Tomb-sweeping Day or the Grain Rain in April, the sowing depth is commonly 0.15 to 0.20 meter, and 4000 to 4500 plants are planted firstly; the planting density of the corn is four rows per furrow, the row width is 0.5 meter, and the planting distance is 0.3 meter, dibble seeding is the main sowing style and each hole is filled with 3 to 4 corn seeds so as to ensure that two plants are planted in each hole after seedling emergence, and 4000 to 4500 plants are planted firstly; The invention can reduce the occurrence of plant diseases and insect pests, improve the yield per unit area, ensure the food security and alleviate the continuous cropping obstacles.

Description

technical field [0001] The invention relates to the intercropping and interplanting cultivation technology of crops, in particular to the konjac and corn alternate belt cultivation technology, and belongs to the technical field of crop cultivation. Background technique [0002] Konjac, also known as medicinal konjac, konjac, pedicel lotus, snake corn, snakehead grass, etc., is a perennial herb of the genus Konjac in the Araceae family. It is a special economic crop containing a large amount of glucomannan in nature. It is used in food, medicine, health care, Industrial materials and other aspects have a wide range of uses. In recent years, the demand for konjac and its processed products in domestic and foreign markets has been increasing, and there has been a situation in which the supply exceeds demand, making the konjac industry a sunrise industry in the 21st century. With the expansion of the scale of konjac planting industry, there have been problems such as serious deg...
